I could roll either way with that. I heard that Saturday was "Be kind to your shoulder day"? Don't know that's true or not.
I have an acquaintance who owns an old slug gun that weighs about 40#. .56 caliber and he does his plinking with a 900 grain bullet. When he gets serious it uses a 1,300 grain 2 piece swagged bullet. I've watched him shoot with the 900 grain load w/250 grains of powder....ouch. My heaviest is a .50 that weighs 600 grains. I'm a puzzy.
Far right is the 900 grain monster. Next to it is a 800 gr .50 cal another friend shoots.
The .56 monster...in the back. You would not believe how well that thing shoots.
